Just like any company, some people have bad experiences, some have good. Felt like I should share the good.
I have ordered from Shutterfly SEVERAL times to say the least. Most recently, I orders various print sizes of images from my honeymoon. I got all my photos, they were exactly as they should be, all the right images and sizes, EXCEPT one order of 2 12x12 images. The box had clearly been injured and taped back up, but not before putting a dent and a scratch in both images. I immediately took pictures of the box and the photos, emailed Shutterfly to explain what happened, and figured I would have to wait for awhile. I got an email confirmation for a reorder of those 2 images (no charge) within a half hour of submitting my email. Then got the follow up from their customer service apologizing for the inconvenience and letting me know they were replacing the photos.
That kind of customer service you can't get just anywhere anymore. Very happy with my experiences with Shutterfly, don't know that I will order from anywhere else.
